    Cummins CSP4/CSP5 Pass Through Switch:

    CSP4/5 pass through switch allows you to change power levels on the go, or commonly referred to "Switch on The Fly". They do NOT require you to stop the truck and wait 5 minutes for the truck to re-flash, you just turn the rotary dial to the position of the tune you want while the truck is running or driving down the road and carry on. These switches plug into the OBDII port and have a pass through port allowing you to plug something else with a OBDII plug into it, such as a Monitor.
